Part H0064001866 is the genuine Haier defrost heater, a 220-230V heater wire that melts frost off the evaporator during each defrost cycle. It's listed for the HRF520 range, including the HRF520BS, HRF520FS and HRF520BHC, the HRF450 range such as the HRF450BS2 and HRF450BW2, and the HBM450SA1, HBM450HSA1 and HBM450WH1.\u003c\/p\u003e\n\u003ch2\u003eSigns the defrost heater in your Haier fridge has failed\u003c\/h2\u003e\n\u003cp\u003eFrost free fridges build up a thin layer of ice on the evaporator as they run. At set intervals the defrost system switches this heater on to melt it, and the water runs away down the drain. If the heater wire goes open circuit, the ice keeps building until it blocks the air path. You'll often find the freezer still cold for a while but the fridge section slowly warming, a solid sheet of ice behind the freezer panel, fans scraping on ice, or water pooling as the ice melts at odd times. A continuity test on the heater confirms it.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Haier part H0064001866\u003c\/li\u003e\n\u003cli\u003eHeater wire style defrost heater\u003c\/li\u003e\n\u003cli\u003eRated 220-230V\u003c\/li\u003e\n\u003cli\u003eListed for HRF520, HRF450 and HBM450 models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e220-230V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eHeater wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eReplacing the defrost heater\u003c\/h2\u003e\n\u003cp\u003eUnplug the fridge, empty the freezer and let all the ice melt before you start. Never chip at it with a tool, as the evaporator tubing is easy to puncture. Remove the rear freezer panel to reach the evaporator. Photograph how the heater is clipped and how its lead is routed, then fit the new one the same way. Test the old heater with a multimeter first so you know it was the fault.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eWhy does my Haier freezer keep icing up at the back?\u003c\/h3\u003e\u003cp\u003eIce packing over the rear panel usually means the defrost cycle isn't clearing the evaporator. A failed defrost heater is a common cause, though the defrost sensor or the control board can also be at fault, so test the heater for continuity before ordering.\u003c\/p\u003e","brand":"Haier","offers":[{"title":"Default Title","offer_id":44549509120078,"sku":"H0064001866","price":131.26,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/h0064001866-genuine-haier-fridge-defrost-heater-220-230v.jpg?v=1792026121","url":"https:\/\/partsshop.com.au\/products\/h0064001866-genuine-haier-fridge-defrost-heater-220-230v","provider":"My Store","version":"1.0","type":"link"}
